U RlNAL-TRAP.

SPECIFICATION forming part of Letters Patent N o. 730,227, dated June 9, 1903. Application filed August 11, 1902. Serial No. 119,277. (No model.)

To all whom it may concern:

Be it known that I, JOS PH H. BRADY, a citizen of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Urinal-Traps; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as willvenable'others to make and use the same, reference being had to the accompanying drawings,- forming a part of this specification.

The object of my invention is a trap for urinals, whereby the outward passage of the sewer-gas t the ventilating-pipe is facilitated and rubbish and oifal deposited in the uri-r nal-basin is intercepted in its course to the sewer.

The invention consists in the novel con-l struction and'combination of parts, such as will be first fully described and specifically.

' tending within' the upper endof thepipe' C,

. pointed out in the claims.

In the drawings, Figure 1 is a View in perspective of the urinal and ventilating case or receiver, a portion of the side wall of the receiver being broken away to show the partition and trap, also showing a portion of the sewer-pipe and'the ventilating-pipe. Fig. 2 is a longitudinal vertical sectional View of the invention as seen in Fig. 1. 3 is a sectional view of the urinal-basin taken upon the line mm of Fig. 2. Fig. 4 is a front view' in detail of the trap.

Similar lettersof reference. indicate corresponding parts in all the figures of the draw- 1ngs.

Referring to the drawings, A represents a urinal trough or basin of the requisite length, the sides a a of which are semicircular in cross-section and upon the ends of which are the flanges a at, extending outwardly from the outer surface of the sides. Upon the outer end of the basin and bolted to the flange a is an end-closing plate o The urinal-basin is preferably arranged upon the floor of the closet or apartment, although the capabilities of the invention are such that the basin may be elevated in position at any desired height above the floor.

B represents the ventilating case or receiver containing the water-trap, which consists of a rectangular-shaped receptacle or case B, the sides I) Z) of which are vertical in position. The forward end of the receiver consists of a neck I), which is semicircular in cross'sec'tion and of the same proportions as the urinal-basin A, upon the forward end of which neck is an outwardly-extended flange b which is bolted to the flange a on the rear end of the basin. The outwardly-curved bottomb of the receiver'extends from the flange b at the forward end of the neck I), thence rearwardly in a downwardly-inclined plane, the sides b I) also extending downwardly and connecting with the bottom and with the rear end M, which also extends downwardly, and which parts 19 and b terminate in a circular neck 19 which neck extends downwardly a short distance from a position adjacent to said rear end in an inwardly and downwardly curved line, the lower end of the said neck exheight above the line of the top of the basin A,-so as to form an air-chamber within the case, and the forward end bi of the receiver extends downwardly from the line of the upper ends of the sides bb to, the plate Z) and is connected therewith, ;W-ithin the receiver B is a transverse partition b extending from the inner surface of the bottom b of the receiver at a point a short distance forward of the neck b upwardly the height of the sides I) b of said receiver, and from the inner surface of one side to the inner surface of the other side of said receiverfthus dividing the receiver into the separate watenretaining chamber b and the ventilating-chain ber b. Upon the inner sides and upper end portions of the ends I) b are the lugs b b and upon both sides of the partition 19 at said upper end are lugs I2 The top of the receiver consists of separate flat plates o b, the portion Z) extending from the forward end I) to a point in a vertical line with the partition b and secured to the lugs b" I) by the screws b'. The portion I) of the top ex tends from the rear end of the portion (1 to and slightly beyond the line of the outer surface of the rear end I) of the receiver, both portions Z) I) of the top also extending a short distance beyond the lines of the outer surfaces of the sides D b of said receiver. In the partition Z), at a point equidistant from the sides I) Z) and in line horizontally with the inner surface of the bottom of the basin A and the inner surface of the plate I) in the neck I) of the receiver, is an elliptical opening Z). Upon the side of the partition 0 within the chamber b and in the direction of the neck I) of the receiver is a water-pipe elbow or trap D, upon the upper end of which is a laterally-extended flange cl, which is secured to the plate b around the opening I)", by the screw-threaded bolts rl,which extend through said plate and the flange (l and are provided with the nuts (Z Between the flange (l and the plate Z1 is a rubber gasket (1.

' In the rear end I)" of the receiver,a short dis tance above the line of the opening I)" for the elbow D, is a small-sized opening I), around which, in the outer surface of the said end, is an annular neck 1) in which is fitted the lower end of a ventilating-pipe E, which is bent at right angles at c and extended upwardly through the roof of the building in the usual manner.

In operation water is supplied to the basin A from any suitable source and at such intervals as maybe desirable to flush the urinal. The quantity of water in the chamber b necessary to form a seal to prevent the passage of the sewer-gas extends in height from the inner surface of the bottom Z)" to the level of the inner surface of the bottom of the basin A, the lower end of the elbow D extending downwardly a short distance below the upper surface of the water-level, and thus trapping the excess of water rising above the level of the bottom of the urinal-basin, the gases passing from the vcntilating-chamber to the ventilating-pipe E direct.

The ventilating case or receiver containing the trap is adapted for large buildings as well as school-houses, where thebasin A is frequently the receptacle for trash and which may be removed without choking the sewerpipe by the removal of the top and extracting the rubbish.

in my former Letters Patent, N 0. 508,899, dated February 15, 1898, the water in the receiver, when the trap becomes clogged, will overflow and no resistance to the further entry of the water into the receiver is afforded.

In the present invention when the trap becomes partially clogged by waste and the water rises to the height of the top of the urinal the air which is above the water in the top of the case or receiver B forward of the partition 0 acts to check the flow of the water and its pressure is downward, so that while the slow movement of the water through the trap is taking place the draft of the ventilating-chamber will assist the flow of the water and the further stoppage of the trap by waste or rubbish from the urinal or basil prevented.

I am aware of the patent to Clifford, No. 358,651, dated March 1, 1887, and to lVillis and Jordan, No. 573,744, dated December 22, 1896. I11 the former patent no Ventilating case or trap is employed and the stoppage of the strainer overflows the basin without assistance being rendered to the water to prevent the overflow. In the latter patent the discharge from the latrine is direct into the sewer and the rubbish in the latrine will choke the outlet-pipe, as in other well-known latri n e I am not aware of a closed air-chamber formed within a ventilating-case above the trap, as in my invention, the results being obviously in a rapid flow of the water from the urinal-basin and its rise above the trap to increase the hydraulic pressure at the entrance to the trap.

Such modifications may be employed as are within the scope of the invention,

IIaving fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is

1. A receiver for urinals and range-closets consisting of a case having a closed top a water-chamber and a sewage-chamb er, a neck extending horizontally from the forward end of the case near its bottom above the opening in which neck within the case is formed an air-chamber the bottom of said case inclining downwardly and rearwardly from said neck outwardly-extended flanges on the outer end of said neck, a transverse partition separating the chamber for air and water from the sewage-chamber having an opening to the sewage-chamber in a horizontal line with the opening in the said neck, an elbow pipe or trap having one end extending around said opening in said partition a draft-pipe connected with the upper portion and rear end of said case and a separate neck in the bottom of said case leading from the sewagechamber which neck extends downwardly a short distance froma position adjacent to the rear end of the case in an inwardly-curved line substantially as described.

2. A receiver for urinals and range-closets consisting of a case having a water-receivin chamber and a chamber for the sewage a neck at the forward end of said case near its bottom, said bottom. being inclined downwardly and rearwardly a transverse partition separating the water-receiving chamber from the sewage-chamber having an opening for the sewage and a trap or'elbow-having the line of the discharge-opening in the said one end extending around said. opening a partition. discharge-opening in the sewage-chamber leading to the sewer and a draft-pipe eon- JOSEPH BRADY 5 neeted with the rearend of said case the Witnesses:
